pupet tool ; it was working in the previous version, it does not work in this version i updated
the image disappears in some frames, the animation deteriorates, you need to constantly repair, I prefer the previous version.
do you mean the asset warp tool?
if so, it works for me.
if you think you have found a reproducible bug, create a new fla and use the minimum number of steps to re-create the bug. then explain each step.
i'm not going to download your file and if you can't explain the steps to reproduce i don't see how you can get any help here.
you could report the issue to adobe but you'll need to explain the steps there, https://www.adobe.com/products/wishform.html
